Pull up Siri and ask these two things:
– How many days since December 17th?
and:
– How many days since December 17th, 2018?
You’ll get two different responses. Now go read the linked post. Very interesting.

Asking “How many days ago was December 17th” comes up with the correct answer.
I’ve run into cases in the past where the math was simply wrong, or right at least in a wild way. “Days ago,” for instance, used to function based on time rather than calendar days and truncate. So if you asked how long ago something one day and 13 hours ago was, it’d say one day (and wouldn’t mention the hours). Which is technically correct from a certain point of view, but utterly useless.
I was poking around just now and couldn’t find the obvious causes of this anymore, but I’m sure there’s still some.
